Are you trying to show music on screen with audio playback? Package them together on YouTube and send a link to your kids. Solved.

Are you trying to play music at the same time as students? You will need to ignore what you hear from the students due to latency. If you play with a metronome, however, the students will be able to play with you (albiet observably late from your end).

Because processing and transmitting audio is much easier and faster than video. Unless both computers are rather powerful and are on the same hardwired network, there will be latency, and you can't fix that.

How do you fix that 1 count delay between seeing the music and hearing the music? The curser is always behind the music.
